A multi-zone, one trip completion system for a wellbore is described. A plurality of isolation packers is installed in borehole to isolate a plurality of zones of the annulus between a tubing string and a wellbore. Each tubing string section is positioned in a zone and comprises a selectively openable stimulation port to provide stimulation fluid to its zone and a selectively openable production port to receive fluid from its zone. The system also comprises a circulation system with a plurality of circulation tubes and circulation tube valves, being configurable in a plurality of configurations to selectively connect, via a circulation flow path, the central bore or the borehole annulus of a wellbore at each of the plurality of sections, to an upper circulation flow path open to an annulus above an uppermost of the plurality of isolation packers.

A technique facilitates formation of a gravel pack. A well completion is provided to facilitate improved gravel packing during a gravel packing operation and subsequent production. The well completion is constructed to freely return a gravel pack carrier fluid through a base pipe during gravel packing. A valve system is positioned to enable restriction of fluid flow into the base pipe following the gravel packing operation. The valve system may be selectively actuated to restrict the fluid flow into the base pipe via a signal such as a pressure signal or timed electric signal.

An apparatus for controlling fluid flow into a well includes an outer tubular member and an inner tubular member. The outer tubular member includes a screen configured to enable fluid flow therethrough between an exterior and an interior of the outer tubular member. The inner tubular member is configured to be positionable within the outer tubular member. The inner tubular member is a remotely activated flow control device configured to control fluid flow between an exterior and an interior of the inner tubular member.

Completion Systems and Methods to Perform Completion Operations are disclosed. A completion system includes a tubular having a wall that defines a flowbore within the tubular and extending into a zone of an annular region external to the tubular. The completion system also includes a first port disposed in the wall and configured to provide fluid communication between the flowbore and the annular region, and a communication path disposed at least partially within the wall and configured to provide fluid communication with an annulus of a well outside of the zone. The completion system further includes a second port disposed in the wall and configured to provide fluid communication between the flowbore and the communication path, a cover disposed over the second port and configured to prevent fluid communication during a fracturing operation, and a diverter seat disposed in the flowbore of the tubular uphole of the second port.

Provided is method for gravel packing dual zones within a wellbore and integrating a zonal isolation system. The method, in one embodiment, includes creating an outer sub-assembly and an inner sub-assembly, wherein the inner sub-assembly is positioned within the outer sub-assembly. The method further includes running the outer sub-assembly proximate a bottom of a downhole portion of a wellbore, and setting an uphole packer in an uphole portion of the wellbore and a downhole packer in the downhole portion of the wellbore. The method further includes gravel packing an upper zone and a lower zone, pulling the gravel pack service tool assembly out of the wellbore thereby isolating the upper zone and the lower zone from each other and the wellbore, and running an upper completion into the wellbore to open one or both of the upper zone or the lower zone for production.

A system for determining positions of a sand control service tool includes a wash pipe positioned below the sand control service tool. The system further includes a sensor attached to the wash pipe. The system also includes one or more magnets attached to downhole completion equipment. The sensor is configured to generate position indicator information that indicates whether the one or more magnets are within a threshold distance from the sensor. A crossover port of the sand control service tool is positioned above a sand control packer when the one or more magnets are within the threshold distance from the sensor.

Various systems, methods, and devices are disclosed for handling contaminants in a wellbore or riser. A washpipe debris trap (WPDT) traps contaminants traveling up a wellbore from a downhole location, and the WPDT may serve as an indicator for a breached screen in a downhole location. A marine riser reversing tool (MRRT) may reverse the flow of fluid between a workstring conduit and an annulus between the workstring and the wellbore such that fluid rises to the wellhead with greater velocity. A bi-directional chamber trap (BDCT) may be utilized in a wellbore operation to remove contaminants from a fluid.

Switchable cross-over systems, devices, and methods for cementing well walls are provided. A switchable cross-over device includes a tool body and a flow sleeve. The tool body includes a main tool path separable into uphole and downhole tool paths and an auxiliary chamber containing uphole and downhole annular ports. The flow sleeve is within the auxiliary chamber and movable between conventional and reverse circulation positions. In the conventional circulation position, the uphole and downhole tool paths are in fluid communication and the uphole annular port is in fluid communication with the downhole annular port through the auxiliary chamber. In the reverse circulation position, the flow sleeve forms first and second auxiliary flow paths in the auxiliary chamber, the uphole tool path and the downhole annular port are in fluid communication via the first auxiliary flow path, and the downhole tool path is in fluid communication with the uphole annular port.

A technique facilitates performance of a gravel packing operation and desired zonal isolation. An apparatus, e.g. a sliding sleeve shunt tube isolation valve, may be deployed downhole and configured to facilitate a gravel packing operation and zonal isolation. By way of example, the apparatus contains a conduit which in an open position allows the flow of gravel pack slurry and in a closed position creates a barrier. In the closed position, upper and lower portions of the conduit are isolated from one another. When the apparatus is coupled with a packer and sand screens, the apparatus serves to create complete zonal isolation in, for example, an open hole alternate path system.

A well tool assembly can include a well screen configured to filter fluid flow between an interior and an exterior of a tubular string, and an outflow control section that permits the fluid flow in an outward direction and prevents the fluid flow in an inward direction, the outflow control section including at least two outflow control valves arranged in series. A method can include installing a well tool assembly including a well screen, flowing a fluid from an exterior to an interior of a tubular string through the well screen and an inflow control valve of the well tool assembly, and flowing another fluid from the interior to the exterior of the tubular string through the well screen and at least one outflow control valve of the well tool assembly.
